Patented Apr. 23, 1940 UNITED STATES PATENT .OFFICE SHOE Chester D. Turner, Haverhill, Mass, assignor to United Shoe MachineryCorporation, Borough of Flemington, N. J., a corporation of New Jersey Application January 4,

1 Claim.

This-invention relates to shoes and shoemaking and, more particularly, to improvements in.

'fieshy, the loose surface fibers held by the cement tearing away from the sole.

It is a principal object of my invention, therefore, to provide an improved shoe in which the cement bond securing the sole is strongly reinforced at the toe portion by invisible supplemental'means securing the sole more permanently to the shoe. Another principal object is to provide a simple and practical method of l constructing shoes embodying my improvement,

and other and further objects will the following specification.

The invention will now be explained with reference to the accompanying drawing, in which: Fig. 1 is a side elevation of the forepart of a appear from lasted shoe having a cement attached extension sole'prepared in accordance with my invention, the toe portion of the shoe being shown in crosssection;

Fig. 2 is a view similar to Fig. 1 disclosing the manner and means whereby the adhesive bond securing the sole is supplemented and reinforced;

Fig. 3 is a perspective view of the shoe in the same condition illustrated in Fig. 2 and clearly shows a preferred arrangement of supplementary metallic fasteners; and

Fig. 4 is another view similar to Fig, 1, disclosing the finished shoe.

In carrying out my improvement, the tread sole ll] of the shoe is split into two portions at the toe, an inner portion i I and an integral outer portion or flap i2, effected before. the sole is cemented to the shoe and extending rearwardly from the toe end throughout the toe portion to the tip line. After attachment of the sole, the flap I2 is turned back, as shown in Figs. 2 and 3, and a plurality of metallic fasteners, such as staples or tacks l5,

are driven through the sole portion I l, the margin it of the upper, and the insole l1, and are clinched at their inner ends against a metal toe the split preferably being- 1938, Serial No. 183,333 (01. 36-12) plate 2| carried on the bottom of thelast 2B, the tacks or fasteners being preferably spaced and arranged about the toe portionof the shoe substantially as illustrated in Fig. 3. The outer portion or flap I 2 is then restored and secured in its original relation to the portion II, as by cement, thereby covering the tacks and rendering them invisible.

In order to provide a finished surface on the flesh side of the sole extension l8 in shoes of this type, and in order to reinforce the extension edge against curling, I prefer to apply a welt 22 over the edge, securing the welt in place by stitching 24 in the manner usual in applying welts to shoes of stitchdown construction, the stitches being aloft both on the welt and on the 1 tread surface of the sole, as shown. Where this is done the stitching may be relied upon to secure the split portions of the sole together without recourse to the use of cement, except that an application of latex or other light adhesive will be found desirable for holding the flap in place preparatory to stitching the welt in position. I

The remaining operations necessary to finish vformed in theusual manner.

In shoes thus constructed, the supplemental sole attaching means will be found'to afford excellent reinforcement for the cement bond prithe shoe, including removal of the last, are permarily relied upon to secure the outsole to the shoe, any tendency for the sole to tear loose being effectively resisted by the metallic fas- I teners.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

In a shoe having a cement attached extension.

sole, the improvement characterized by the sole being split rearwardly from the toe end to the tip line only to define an integral flap on the tread side thereof, a plurality of metallic fasteners extending through the remaining toe portion of the sole and through the cement into the shoe, 2. welt overlying the edge extension of the sole, and a line of stitching extending through said welt, edge extension, and flap, to secure the welt and flap in position, the cement bond between the shoe and sole being solely relied upon to hold the shoe and sole'together except at the toe portion where the metallic fasteners are inserted.
